Teridax was the main antagonist in the Official Bionicle Storyline, but isn't a character in any of TSO1's videos. Although, in Phantoka #16 - House of the Dead, Antroz mentions Teridax at one point. He was mentioned again when Chirox was fustrated by the fact that Antroz wasn't too pleased of the gift with the Shadow Matoran he gave him. He asked Antroz who said he was the leader anyway and Antroz replied with Teridax's name. Chirox reminded Antroz that Teridax wasn't here and rejected Antroz's reply.
